Abstract
For the purpose of global modeling of water use and crop production, a digital global map of
irrigated areas was developed. The map depicts the percentage of each 0.5° by 0.5° cell that
was equipped for irrigation around 1995. The first version of the map has now been updated
and improved for Latin America (including the Caribbean) and Europe, based on 1) new
information from FAO`s AQUASTAT and FAOSTAT, 2) national data on irrigation in subnational units 3) geographic information on the location and extent of irrigated areas and 4)
the European land cover map CORINE. The total irrigated area per country has changed
considerably in many countries, especially in Latin America where the information acquired
by FAO for the new AQUASTAT report is now included. In total, irrigated area has increased
by 0.4% in Latin America as compared to the first version of the map, while it has decreased
by 4.5% in Europe. Compared to the first version of the map, the spatial resolution of the
input data is much higher, and the new maps show a more disperse irrigation. This
documentation describes the data sources and the map generation process of the new maps for
Latin America and Europe, and discusses the map quality.

share their information on irrigation in Latin America.

Overview
The digital global map of irrigated areas is a raster map with a resolution of 0.5° latitude by
0.5° longitude. For the whole land area of the globe (except Antarctica), the data set provides
the irrigation density around 1995, i.e. the percentage of each 0.5 ° by 0.5 ° cell area that was
equipped for controlled irrigation in the 1990s. The areas equipped for irrigation include
• areas with full or partial control irrigation
• spate irrigation areas and
• equipped wetlands and inland valley bottoms.
They do not include cultivated wetlands and flood recession cropping areas. In such areas
there is a lack of control over the application of water, and thus irrigation water use cannot be
computed as the optimal irrigation requirement. The area actually irrigated was smaller than
the area that was equipped for irrigation, but is unknown for most countries. In the following,
"irrigated areas" always stands for "areas equipped for irrigation".
The first version of the map was derived by combining information from large-scale maps
with outlines of irrigated areas (one or more countries per map), FAO data on total irrigated
area per country around 1995 and national data on total irrigated area per county, drainage
basin or federal state. Irrigation density was modeled on a 5’ (0.0833°) raster and later
aggregated to a 0.5° raster. The first version is documented in Döll and Siebert (2000, 1999).
Here, we present an updated version of the map for Latin America and Europe. In the
following, Latin America always includes the Caribbean. The update is based on improved
and more detailed data; besides, a different method was used for the map generation. The map
is representative for the situation in the 1990s. Information mainly from the years 1990 to
1999 was taken into account, depending on the country or sub-national unit. For the map of
Latin America, new information gathered by FAO for the AQUASTAT report on irrigation in
Latin America (FAO, 2000) was used. Information included both the total irrigated area in a
high number of sub-national units (e.g. counties, federal states) and geographical information
on the location and extent of irrigation. For the map of Europe, new national information and
literature data on total irrigated area in sub-national units and new geographical information
was used, as well as the CORINE land cover data set (European Environmental Agency,
2000). Latin America was divided into 395 (sub)-national units (Table B1) and Europe into
174 (Table B3). The geographic information applied to derive the new maps did not only
include outlines of irrigated areas (polygon data) but also information on irrigation projects
(point information) and raster information (CORINE database). Table 1 shows the different
types of geographic records. We derived new rules for distributing the total irrigated area
within the sub-national units to the various geographic records within this unit. In order to
facilitate the distribution, we assigned a priority level to each record, based on the type and
the reliability of the information (see Table B2 for Latin America and Table B4 for Europe).
Irrigation density was modeled on a 0.01° raster, and then aggregated to the 0.5° raster.

Map generation
For many countries, information on the total irrigated area in sub-national units has been
included for generating the new maps for Latin America and Europe (Section 2.1). For most
countries, different types of geographic records were available (Tables B2 and B4 in
Appendix B). As their relevance and reliability vary, it is necessary to decide which
geographic records are taken into account. In Section 2.2, we describe how the geographic
information was selected for each sub-national unit. Once we know which records are used to
generate the map, we distribute the irrigated area related to the geographic records to the
individual grid cells. This procedure is described in chapter 2.3.
2.1
Determination of irrigated area in sub-national units
In the case of Latin America, information about the irrigated area in sub-national units (Table
B1 in Appendix B) stems from national statistics collected by FAO to compile the
AQUASTAT report on irrigation in Latin America and the Caribbean (FAO, 2000). It is
provided for all the large and many of the small countries of Latin America (and the
Caribbean). In the cases where the sum of the irrigated areas in the sub-national units,
according to the original national statistics, was not equal to the total irrigated area of the
country as given in FAO (2000), the values for the sub-national units were adjusted
correspondingly. For Europe, information on the distribution of irrigation within countries is
not available from FAO. For Russia and Germany, we obtained national statistics of irrigated
area in sub-national units (Table B3 in Appendix B). For France, Italy and Portugal, literature
values of irrigated area of sub-national units have been adjusted such that their sum is equal to
the latest FAOSTAT country value (www.fao.org).

2.2
Selection of the geographical information to distribute total irrigated area within
each sub-national unit
For the map generation process, Latin America was divided into 395 and Europe into 174
(sub)-national units (for simplicity, we also call countries, for which no sub-national units are
defined, “sub-national units”). A list of these units and the total irrigated area within these
units can be found in Appendices B1 and B3. Appendices B2 and B4 list, for each country,
the geographical information records that are available to distribute the total irrigated area
within the (sub)-national units, and their priority level. The priority level (the highest priority
being represented by a value of 10) was introduced to control the distribution process. Only if
the total area of all geographical records of priority 10 is smaller than the total irrigated area
in the sub-national unit, the geographical records of priority 9 (or lower) are also taken into
account.
In general, priorities are assigned as follows. The highest priority is given to point records
(irrigation projects) with known irrigated area, followed by point records without size
information. Polygon records (outlines of large irrigated areas) with size information get the
next lower priority, which is again higher than that of polygon records without size
information. Auxiliary information like information of the growing area of certain crops
becomes an even lower priority level. Information on the location of surface irrigation from
the CORINE data set1 for Europe has always been given priority 10. Priorities are assigned
with respect to the specific sub-national unit in which the geographic record is located.
In order to determine which geographic information on the location of irrigated areas within a
sub-national unit is taken into account, the value for the total irrigated area within a subnational unit as stated in literature AILIT (Tables B1 and B3) is compared to AIDB, the sum
of all areas in a sub-national unit that are potentially irrigated according to the geographical
information in Tables B2 and B4. To compute AIDB we have to make assumptions for
polygon and point records without information about the irrigation density within the polygon
or the size of the irrigation scheme represent by the point record. We assume that the
irrigation density within the areas with known outlines is 100% and that each point record
represents an irrigated area that is equal to the size of the 0.01° cell in which it is located (80–
120 ha).
If, for a certain sub-national unit, AIDB≤AILIT, all available geographic records are used.
AIDB>AILIT occurs, for instance, in sub-national units with many irrigated areas with known
outlines but unknown irrigation density or in cases where there are also records on special
land use (cotton, rice). In this case, only the geographic records with the highest priority
levels are used. The sum of areas of all geographic records with the same priority level AIDBp
within the sub-national unit is calculated. Then, there exists a priority level p’ such that:
10
∑ AIDB p ≤ AILIT
p = p ' +1
10
and
∑ AIDB
p= p'
p
> AILIT

The CORINE data set contains information on land use and land cover types for most European countries. We
used a raster file which distinguishes 44 different land cover types on a 250 m grid. We assumed that CORINE
land cover types 13 (permanently irrigated land) and 14 (rice fields) are irrigated. Probably, only surface
irrigation is covered by the CORINE data set which, for example, shows no irrigated areas in Germany or the
Netherlands, see Table B4). In order to facilitate data handling, the raster file was converted to a point data file
by creating one point in the middle of each CORINE cell with land cover type 13 or 14. Because of the cell size
(250 m x 250 m) each of these points represents 6.25 ha irrigated land. The map projection was changed from
Lambert to Geographical Projection, and the sum of all areas of all CORINE points located within a 0.01° cell
was assigned to a point in the center of the cell. Altogether, there are 84 667 irrigated 0.01° cells in Europe.

To distribute irrigated area within the sub-national unit, all geographical records having a
priority level higher than p’ are used, while records having an information priority lower than
p’ are ignored. Geographical records having a priority of p’ are used, but their irrigation
density is decreased such that:
10
∑
p = p ' +1
AIDB p +
d
∗ AIDB p ' = AILIT
100
( 0 < d < 100 )
(2)
An example illustrates the procedure in the case that AIDB>AILIT. In a given sub-national
unit there are
a) 7 irrigation projects (point records) of known area (in total 4000 ha), priority 10
b) 3 point records referring to 1000 ha irrigated rice, priority 9
c) 10 irrigation projects (point records) without size information (assuming that each
irrigation project covers one 0.01° grid cell: in total 1100 ha), priority 8
d) 3 irrigated areas (polygon records), area information available (known irrigation density
within these areas), in total 900 ha, priority 8
e) 2 irrigated areas without size information (irrigation density within these areas unknown,
is assumed to be 100%), in total 10000 ha, priority 7
f) 1 potential irrigated area, area information not available (pot. irrigation density unknown,
is assumed to be 100%), 12000 ha, priority 6
The total irrigated area within the sub-national unit is 10000 ha. According to a - f we could
distribute 31000 ha irrigated area within this sub-national unit. This is much more than stated
in literature, so we have to select the most reliable information. There are 4000 ha with
priority 10, 3000 ha with priority 9, 2000 ha with priority 8, 10000 ha with priority 7 and
12000 ha with priority 6. According to (1) and (2) all records having a priority of 10, 9 and 8
are included completely, records with priority 6 are ignored. Records with 7 are all taken into
account, but with reduced irrigation density. As the sum of the area in records with priority
10, 9 or 8 is 9000 ha, the remaining 1000 ha are distributed to records with priority 7. As the
outlines of the two irrigated areas in our example cover a total area of 10 000 ha, the irrigation
density in these areas is reduced to 10%.
2.3
Distribution of irrigated area to single grid cells
After the above steps, there exists a list of point or polygon geographical information which
now includes also the size of the irrigated area. In the next step, the vector-based information
is transferred to a raster-based irrigation density map.
2.3.1 Point data
Irrigated area related to point data is assigned to the 0.01° grid cell in which the point is
located. If the irrigated area of such a project is bigger than the cell size, then this difference is
distributed to the neighbor cells in proportion to the cell size of the neighbor cells (with same
irrigation density).

Example:
A B C
D E F
G H I
2.3.2
The size of cells A-C is 86.5 ha, the size of cells D-E 86 ha and that of cells G-I
85.5 ha. In cell E, an irrigation project (size 258 ha) is located. Then, 86 ha are
assigned to cell E, 21.625 ha each to cells A-C, 21.5 ha each to cells D and F
and 21.375 each ha to cells G-I. The irrigation density in cell E is 100%, the
irrigation density in the other cells 25%.
Polygon data
The irrigated area related to a given polygon is distributed to all cells inside the polygon in
proportion to their cell areas. However, if irrigated area from a record with a higher priority
level has already been assigned to the cell, the cell is excluded from the distribution process.
There is an exception to this rule in the case of point records derived from the CORINE data
set for Europe, which represent surface area irrigation. If a part of a 0.01° cell is covered by
surface irrigation, then in other parts of this cell other irrigation methods could be applied.
Therefore, these cells were not excluded from the distribution process. The following
examples illustrate the applied distribution method.
Examples:
Let us assume that a polygon that represents an irrigated area covers the grid cells A, B, C and
D (priority level 9). The size of the grid cells A and B is about 102 ha, the size of the grid
cells C and D about 101 ha. It is known that the area actually equipped for irrigation, within
the irrigated polygon, is 126 ha.
Example 1 in Latin America
Example 2 in Europe
In cell A there is an irrigation project with 50 According to the CORINE database there are
50 ha surface irrigation in cell A (priority

level 10).
step 1: 50 ha of irrigated area (the irrigation step 1: 50 ha surface irrigation is assigned to
cell A.
project) is assigned to cell A.
step 2: The remaining 76 ha are distributed to
cells B, C and D in proportion to their cell
areas. Thus, there are 25.5 ha irrigated area in
cell B, and 25.25 ha both in cells C and D.
step 2: The remaining 76 ha are distributed to
all 4 cells in proportion to the remaining cell
areas (52 ha in cell A, and the total cell areas
of cells B, C and D. Thus, 11.1 ha are
distributed to cell A, 21.77 ha to cell B, 21.56
ha to cell C and 21.56 ha to cell D.
resulting irrigated areas:
cell A: 50 ha; cell B: 25.5 ha; cell C: 25.25
ha; cell D: 25.25 ha. The irrigation density in
cell A is 49% and in cells B,C and D 25%.
resulting irrigated areas:
cell A: 61.1 ha; cell B: 21.77 ha ; cell C:
21.56 ha; cell D: 21.56 ha. The irrigation
density in cell A is 59.9% and in cells B, C
and D 21.34%.

2.3.3
Distribution of irrigated area in proportion to agricultural area (if AIDB<AILIT)
For some sub-national units, the total irrigated area is known (Tables B1 and B3) but not its
location, or only the location of a few small projects. Then the sum of the irrigated area of the
schemes in our database (AIDB) is smaller then the irrigated area within the sub-national unit
according to statistics (AILIT). The question is how to distribute the difference between
AILIT and AIDB to the 0.01° cells within the sub-national unit. We decided to do that in two
steps. First the irrigated area, which is related to point information sources is increased by up
to 100%. If the resulting area is still smaller than AILIT, the remaining difference is
distributed to all grid cells of the sub-national unit in proportion to the agricultural area within
the individual cells. To estimate the agricultural area within the grid cells we used an
unpublished data set by S. Wood and K. Sebastian from the International Food Policy
Research Institute IFPRI which was provided to us in 1999, which describes the fraction of
the total 5-minute cell area that is agricultural area and is based on a 10-km land cover map
from the Eros Data Center (USA). As suggested by S. Wood, we assume that class 1 indicates
80% of the cell is covered with agricultural area. The corresponding values for class 2 and 3
are 50% and 35%.
Example. A sub-national unit consists of only four grid cells A, B, C and D. 71 ha of the
surface area of this sub-national unit are irrigated. The cell size of each of the cells is 100 ha.
In cell B there exists an irrigation project of 25 ha, but there are no further geographic records
available for this unit. 50 ha (25 * 2) are assigned to cell B, while the remaining 21 ha are
distributed among all four cells. According to the IFPRI map, cells A and B belong to class 1
(80% agricultural area) and cells C and D to class 2 (50% agricultural area), and we assume
that in cells A and B there are 80 ha agricultural area and in cells C and D 50 ha. Because 50
ha of irrigated area have already been assigned to cell B, only 30 ha agricultural area in that
cell is available for further distribution. So the whole available agricultural area is 80 ha + 30
ha + 50 ha + 50 ha = 210 ha, and 10% of the remaining agricultural area has to be irrigated
(100*21/210). As a result, in cell A there are 8 ha irrigated (10% of 80% of 100 ha), in cell B
53 ha, in cells C and D 5 ha.

Integration of the new maps for Latin America and Europe into the
existing global irrigation map
The updated version of the digital global map of irrigated areas was constructed by merging
the new maps for Latin America and Europe with the first version of the map for the other
continents. The first version of the global map of irrigated areas was modeled at a resolution
of 5 min, and the new maps for Latin America and Europe at a resolution of 0.01°. The
different resolutions lead to several problems related to the merging of the maps, especially at
the boundaries between the old map and the new maps. Because of the different resolutions,
there are map overlaps. The following steps were taken to avoid double-counting:
1. First version of map: calculate irrigated area in all 5-minute grid cells, in ha, set value of
all 5-minute grid cells belonging to Latin America or Europe to 0, and generate a new grid
at the 0.5° resolution
2. Updated maps for Latin America and Europe: generate grids at the 0.5° resolution which
indicate the irrigated area in each cell, in ha
3. Merge the three 0.5° maps by computing the irrigated area in each grid cell as the sum of
the values of the three maps.
10
A country-wise summation of the irrigated area in all grid cells at the original resolution
would lead exactly to the total irrigated area per country, as stated in literature. This is not the
case for the resulting 0.5° resolution, because the irrigated area of some cells belonging to a
certain country at the original resolution could be assigned to the neighbor country at the 0.5°
resolution. The reason for this is that 0.5° cells as a whole belong to one country.

Discussion
To discuss the results of the map update, we first show the differences between the original
and the new irrigation map for Latin America and Europe. Appendices A1 and A3 show the
old version of the maps for Latin America and Europe, and Appendices A2 and A4 the
updated version. Then, the map quality is discussed.
4.1
Differences between the original map and the updated map
Differences between the original irrigation map (see maps A1 and A3) and the new map (see
maps A2 and A4) are due to
1. changed values for the whole irrigated area in a country
2. different distribution of the irrigated area within a country (due to more sub-national units
that are distinguished and different geographic information on the location and extent of
irrigated areas).
4.1.1
Changed values of the total irrigated area per country
The changes of the irrigated area per country are documented in Table 2 (for Latin America)
and Table 3 (for Europe). In Latin America, there are significant changes as for all countries
AQUASTAT (FAO, 2000) instead of FAOSTAT (http://www.fao.org) values of irrigated area
per country are now used. Different from FAOSTAT data, AQUASTAT data are based on
special country reports on irrigation and drainage, which were obtained by FAO for the
compilation of FAO’s new AQUASTAT report on irrigation in Latin America (FAO, 2000).
Compared to the previous map, there is a strong increase of irrigated area in Ecuador, Chile
and Venezuela and a strong decrease in Brazil and Peru. In many small countries, there are
significant relative decreases, e.g. in El Salvador, Puerto Rico, Trinidad + Tobago, St. Lucia
and St. Vincent. Comparing the new (Fig. A2) with the previous (Fig. A1) map, the increase
of irrigated area in Chile and Ecuador is particularly obvious. In 13 out of the 35 countries
with irrigation infrastructure in Latin America, the irrigated area has changed by more than
20%. At the sub-continental scale, however, increases and decreases almost cancel. In total,
irrigated area has increased by 0.4% in Latin America as compared to the first version of the
map.

For most European countries, the discrepancies of irrigated areas in the previous and in the
new map are smaller than for the Latin America countries. Different from Latin America, we
could not take advantage of new AQUASTAT data. Some discrepancies are due to taking inot
account more recent FAOSTAT data (1994 - 1999). For some countries we use data from
national statistics (UK, Spain, Germany, Russia) instead of FAO data. In the first version of
the global irrigation map, the total irrigated area of Russia was located in the European part of
the country. According to recent national data (GOSCOMSTAT, 1998), 3,983,000 ha
irrigated area are situated in the European part of the country and 885,000 ha in the Asian
part. For Austria we did not use the FAO estimate (4000 ha), because according to Janetschek
(1992) there are 16,000 ha sprinkler irrigation in one important irrigation area (Marchfeld).
Therefore, the estimate of Framji et. al (1984) of 46000 ha irrigated area for Austria appears
to be more realistic. The huge difference in the case of Belgium is due to a correction in the
FAOSTAT database. In 7 out of the 38 countries with irrigation infra structure in Europe, the
irrigated area has changed by more than 20%. In total, irrigated area in Europe has decreased
by 4.5% as compared to the first version of the map.

Changed distribution of irrigated area within the countries
In the previous irrigation map most irrigated area was concentrated in the major irrigation
schemes of a country. This has changed in the most of the countries. The number of irrigated
0.5° cells has increased from 1749 to 3849 in Latin America and from 1091 to 3257 in
Europe. There are two reasons for the more disperse irrigation. First, much more geographical
information on the location of irrigation schemes has been included. Second, information on
the total irrigated area in sub-national units is available for many more countries,. The number
of sub-national units (federal states, districts ...) has increased from 83 to 370 in Latin
America and from 11 to 135 in Europe. As a consequence, irrigated area has to be distributed
within sub-national units, in which no geographic information on the location of irrigation
schemes is available (e.g. in Russia). This leads to a homogeneous distribution of irrigation
over a wide area.
4.2
Discussion of map quality in Latin America and Europe
For the new maps of irrigated areas in Latin America and Europe, more geographic
information about the location of irrigation schemes has been taken into account than for the
generation of the first version of the maps. Besides, improved statistical data with a higher
spatial resolution have been included. Therefore, the quality of the new maps is better than the
quality of the first version. How well the maps represent actual areas that were equipped for
irrigation around 1995 strongly varies between countries, and even within countries,
depending on the quality and quantity of the input information. For example, the quality of the
map certainly depends on the size of the sub-national units. In general, quality is better in
regions where irrigation plays an important role in agriculture, as for such regions there tends
to exist better irrigation-related information.
13
To give an idea of how uncertain the total irrigated area in a sub-national unit (and probably
for the whole country) may be, let us consider the federal state of Ceará in Brazil. For the
purpose of modeling water use Ceará, we estimated that the irrigated area in 1996/98 was
about 43,000 ha, based on licensing information from the state’s water ministry and expert
opinion. Ceará’s agricultural ministry, however, estimates that there are approximately
60,000 ha, while the value given by Brazilian statistics, which is applied in the map, is 77,000
ha. It may be that the lower values correspond to areas that were actually irrigated (and not
just equipped for irrigation) but distinctions between “actually irrigated” and “equipped for
irrigation” are not made explicit.
Although the new global irrigation map is based on much more geographic information than
the previous one, there are still regions in which the distribution of irrigated areas is quite
uncertain, e.g. in large parts of Russia and Brazil, or the Scandinavian countries. Due to the
lack of information on the location of irrigation schemes, the irrigated area in the most subnational units of Russia and in parts of Brazil had to be distributed only in relationship to the
agricultural area. For most of the Eastern European countries the development of the
irrigation sub-sector since 1990 is uncertain, and it is often unknown which irrigation schemes
are still in operation. In many countries, small-scale irrigation plays an important role. So
more than 40,000 farmers irrigate approximately half of the irrigated area in Mexico, and
detailed mapping of all the small irrigation plots seems to be impossible. Nevertheless, the
representation of irrigated areas in Mexico appears to be reasonably good. In a few countries,
we judge the map quality to be very good: in the Caribbean countries, Ecuador and Chile in
Latin America, and in Portugal, Spain and Italy in Europe.
Due to the map uncertainties, we advise to use the global map of irrigated areas only for
global and regional assessments (also in the case of Latin America and Europe). For future
improvements of the map in Africa, Asia, Australia and Oceania, information from remote
sensing projects should be included, in particular in arid and semi-arid regions.
Acknowledgments: We acknowledge the financial support of FAO and their willingness to
share their data on irrigation in Latin America.
